Cross Laminated Film For Bitumen Waterproof Membranes
Description:
It is multi-layers laminated film with high strength property, made
via three layers co-extrusion
film blown process and special stretching technology. The inner
crossed structure differs from
traditional films with one layer or many layers, possesses both
thermal stability and dimensional
stability, good bidirectional tear resistance & high tensile
strength, as well as high elongation
at bi-direction.
The Production Process:
OUR THREE STEP PROCESS FOR MANUFACTURING HIGH STRENGTH, DURABILITY,
AND QUALITY CROSS LAMINATED FILM.
Step 1: FILM BLOWING
Step 2: Spiral Cutting
| Why Cross Laminated? |
| 1. Puncture Resistance: less accidental damage |
| 2. Thermal Dimensional Stability: No fish-mouthing or controlled
shrinkage |
| 3. Cold temperature resistant down to -30°C/-20°C |
| 4. Cross laminated film allows waterproofing membranes to bridge gaps
in sheathing and is resistant to damage from incidental movement
and settling of the roof |
| 5. UV Stability for typical job site exposure |
